Application filed .Tuly 21, 1913. Serial No. 780,243.

To all lwhom 'it may concern.'

Be it known that ALLEN E. OSTRA'NDER, residing at Ridgewood, Bergen county, Newv Jersey, and being a citizen of the United States, have invented certain new and useful Improvements in 'Railway-Trucks, of which the following is a full, clear, and exact description, such as will enable others skilled in the art' to which it appertains to make and to use the same, reference being had to the accompanying drawings, which illustrate thepreferred form of the invention, though it is to be understood that the invention isnot limited to the exact details of construction shown and described, as it is obvious that various modiiications thereof will occur to persons skilled in the art.

In said drawings:

Figure 1 is a side elevational view of a complete truck formed in accordance with the present invention.

Fig. 2 is a vertical sectional view, the section being taken on line 2 2 of Fig. 1., looking in the direction indicated by the arrows,

Fig. 3 is a central vertical longitudinal section through the top archbar casting,

including columns and spring-plank saddle, hereinafter described.

Fig. 4.- is a fragmentary view of' a modiifl cation hereinafter described.

which decrease its eiciency.

One of the objects of the present invention is to 4provide a bottom arch bar of lwrought metal resting at itsvends on the 'journal boxes and of such curvature intermediate the journal boxes as will developthe maximum tensile strength ofy the b'ar, due to the elimination of `angles' therein at its middle portion.

It is well known that wrought metal possesses greater tensile strength than cast metal of equal section, hence the use of wrought metal for the bottom arch bar, which in the truck is a tension member of its side frame, f

Cast metal is especially adaptable for use in the top arch bar, due to its superior eiciency in compression, hence the top arch bar is formed of cast metal, and to simplify the construction of the side frames, the col- Emns arecast integral with the top arch' To provide an arcuate seat )for the long sweeping curve of the bottom arch bar, the two spaced columns of the truck side frame are united by an integral column tie-or spring-plank saddle, and depending from the lower face of the spring-plank saddle is a finger adapted to .engage with an oriiice in the bottom arch bar and the tie bar.

To reinforce the columns and said saddle,

I prefer to cast therein a 'wrought metal spring-plank suspension yoke, which is relatively `Ushaped, as best shown in Fig. 3, and extends within the contiguous portions of the top arch bar.

Another object isl to provide castings, where available, which will be of such form that they may be readilyA handled, and

which may be packed for shipment' in'relatively small space.

Another object is to reduce the number of openings inthe bottom arch bar, which are commonly provided with wrought metal arch bars, and to standardize the parts of the side frame for convenience of repairs,

Asuch as replacement of parts.

.Another ob'ect is'to reinforce the cast portions of the truck, comprising top arch bar, columns and spring-plank saddle, by means of a wrought metal spring-plank suspension yoke,.about which is poured the cast metal in such manner thatthe said springplank suspension yoke is exposed, as j. shown in Fig. 3, thereby providing a smooth and relatively Iinished surface, uponv which may -rest the spring-plank of the truck at the bottom, and against it may be positioned the bolster column guides, commonly used with arch bar trucks. j

Referring specifically to the parts, 1 is the top arch bar or compression member which, as will be noted, extends across the tops of adjacent journal boxes 2-2, in which are journaled the axles upon which the wheels are mounted. l

Cast integral with the top' arch bar are the columns 3 3 and the spring-plank saddle 4 with the depending linger 5, before referred to. The bottom face 6 of the springplank saddle3 is curved in the arc of a circle corresponding to the curvature of the bot- .tom arch bar or extension member 7 and extending downwardly, and longitudinally at t truck side fram,

each side of the arcuate face 6 are depending anges 8, a groove being thus formed in the bottom of said spring-plank saddle, and, hence, the bottom arcuate face 6 is depressed within said saddle. As a result, the bottom arch bar is insured better contact with said bottom arcuate face 6, and the groove also serves to prevent torsional displacement of said bottom arch bar with relation to said spring-plank saddle, the linger 5 being adapted to project through a co-incident orifice in said bottom arch bar for the purpose of positioning` the said parts with relation to each other.

To reinforce the columns 3, and to pro- Yvide a bearing face of greater area, the

spring-plank saddle is extended at each side at 9, thereby providing athickened portion at the base of the columns 3. To reinforce the columns and the spring-plank saddle,-a spring-plank suspension yoke 10 of wrought metal is inserted, as best shown in Fig. 3, the cast metal surrounding said yoke and entirely inclosing it, if desired, though I prefer to employ shown in said Fig. 3, wherein the yoke has hooked ends which are embedded in the top arch bar and extends to the surface, at 11, to provide a fiat smooth bearing for the spring-plank 12, lpon which the usual spring seat 13. aid sp .-pa may extend across the truck rohinie side frame to the other, and its ends may terminate at or near the outer edges of the saddles 4, said ends being shown as being fastened to the saddles on opposite sides of the wrought metal yoke 10. ,The yoke also extends to the surface at 14-14,r or cavities 15 being formed in the columns 3 for the reception of cheek plates or bolster column guides 16, which are removably placed in said recesses 15, and bear against the sides of the Iholsters 17, for well understood purposes Resting upon the spring seats 13 and between said seats and the holsters, are the usual springs 18.

On account of the limits of the cavities in Which the cheek plates or bolsterv column guides 15 are positioned and the relation of guides 16 and the guide members carried by bolsters 17, said guides 16 cannotbe removed until the bolster has been suiiiciently and abnormally displaced by deliberate intention.

Casting the metal comprising the top arch bar columns and spring-plank saddle about #Sfthe spring-plank suspension yoke, as indicated, eliminates the necessity of machining or slrface dressing to receive the springplank and bolster column guid, whichsurface dreing is commonly required in cast due to the somewhat thel specific arrangement roughened surface of the castings as they leave the mold. As seen in Fig. 1, columns 3 of the side frame are provided near their bottoms on their inner sides with offset portions 3a so spaced as to position the end of the spring plank 12 and assist in holding said spring plank in proper position.

Cast integral with the columns 3 are the brake beam hanger pins 20, which.- as shown in Fig. 1, serve as supports for the brake beam hangers 21, with which are connected the brake heads 22 in the usual manner.

The tie bar 23 employed in the present construction is of the conventional type, provided with perforations at its ends for the journal box bolts 24, which journal box bolts extend through the outer ends of the top and bottom arch bars, as indicated in Fig. 3, where a separate journal box is employed, as is customary.

The finger 5 coincides with a suitable orilice in said tie bar 23, which orifice isin alinement with the orifice referred to in the bottom arch bar and, as willbe noted in Figs. 1 and 2, said finger 5/ serves as a means for locking the tie plate and bottom arch bar in position.

To avoid perforating the lower arch bar in its middle portion, it may be formed as shown in Fig. 4, in which 7l indicates a modified form of lower arch bar on which are formed or-secured, preferably by weldlng, the stop lugs 7", which will coact with the shoulders 9 to position the lower arch bar with relation to the spring-plank saddle without the necessity of perfor-ating the said lowerarch bar for bolts or the inger 5.before referred to.
